PROBLEM TO BE SOLVED: To facilitate the cleaning and the exchange of a primary electrifier under the set-in condition of an imaging unit as doing so is difficult for a conventional image forming device which forms an image under the set-in condition at the fixed location of an imaging unit mounted inside a box in which at least a photoreceptor drum, a primary electrifer in the corotron or scorotron type and a developing apparatus are formed all in one. SOLUTION: The primary electrifier of the imaging unit is mounted so as to be pulled out freely in the longitudinal direction against the imaging unit, and the image forming device is furnished with the primary electrifier's pulling- out mouth, from which the primary electrifier can be pulled out under the set-in condition at the fixed location of the imaging unit, and the primary electrifier's pulling-out member.
